Bahrain's state television has broadcast images of the crown prince meeting with top opposition leaders one week after reconciliation talks were suspended.
Opposition bloc al-Wefaq released a statement Monday after the face-to-face with Crown Prince Salman bin Hamad Al Khalifa saying that it hoped the meeting would result in concrete steps.
A participant in the talks, who spoke anonymously because of the sensitivity of the situation, said a U.S diplomat attended the meeting.
It was the first time in nearly three years that a member of the ruling family met leaders of the opposition.
Opposition in Bahrain began protesting in early 2011 to seek greater political rights from the Gulf Arab nation's rulers.
